The quests are kind of "go here, kill that" but there is a lot of lore written into the game world. Combat is more dodge, parry, block then you'd expect rather then just smacking things until they're dead. There's an item crafting system, along with potions and shards you can use to buff weapons.
Graphically it looks really nice. The art design in the game is quite strong with pretty vistas and vibrant colours. However the camera is quite narrow in angle, about 40 degrees I believe, so your character takes up a fair amount of the screen, blocking the nice views a bit. There is at least two mods that can bring the camera angle up, I use one called Widescreen Fixer.
I haven't finished it, and the plot seems rather usual (guy goes evil and threatens world) but the combat can be a nice challenge with the difficulty turned up. Levelling is through experience, though the games quite free with builds, allowing you to rebuild your character from the ground up whenever by visiting certain NPCs. Three classes, fighter/mage/thief, which can be mixed and matched however (So a fighter/mage who wears heavy armour and casts spells, a mage/thief teleports around throwing daggers). Every level you get a point (or three) to put into one of the three class trees. When enough points have been put into a tree you can chose a card that increases your stats in the same angle. So a mage/thief with 30pts in mage and 10 in thief could take a card called Nightblade, next card at 40/15 points.
There's no patches, nor any fanmade mods/patches, so I'd say the games going to be as it is from now until whenever.
